An Individual Participant Data Meta-analysis: Behavioral Treatments for Children and Adolescents With Attention-Deficit/Hyperactivity Disorder
Objective: Behavioral interventions are well established treatments for children with attention-deficit/hyperactivity disorder (ADHD). However, insight into moderators of treatment outcome is limited.Method: We conducted an individual participant data meta-analysis [IPDMA], including data of randomized controlled behavioral intervention trials for individuals with ADHD[less than]18 years. Outcomes were symptoms of ADHD, oppositional defiant disorder (ODD), and conduct disorder (CD) and impairment. Moderators investigated were symptoms and impairment severity, medication use, age, IQ, sex, socioeconomic status, and single parenthood. Results: For raters most proximal to treatment, small to medium sized effects of behavioral interventions were found for symptoms of ADHD, inattention, hyperactivity/impulsivity (HI), ODD and CD, and impairment. Blinded outcomes were only available for small preschool subsamples and limited measures. CD symptoms and/or diagnosis moderated outcome on ADHD, HI, ODD, and CD symptoms. Single parenthood moderated ODD outcome, ADHD severity moderated impairment outcome. Higher baseline CD or ADHD symptoms, a CD diagnosis, and single parenthood were related to worsening of symptoms in the untreated, but not in the treated group, indicating a protective rather than an ameliorative effect of behavioral interventions for these children.Conclusion: Behavioral treatments are effective for reducing ADHD symptoms, behavioral problems, and impairment as reported by raters most proximal to treatment. Those with severe CD or ADHD symptoms, a CD diagnosis, or single parents, should be prioritized for treatment, as they may evidence worsening of symptoms in the absence of intervention
Te Whānau Pou Toru: a Randomized Controlled Trial (RCT) of a Culturally Adapted Low-Intensity Variant of the Triple P-Positive Parenting Program for Indigenous Māori Families in New Zealand
Evidence-based parenting support programs (EBPS) based on social learning and cognitive behavioral principles are effective in reducing conduct-related problems in a diverse range of cultural contexts. However, much less is known about their effects with indigenous families. A Collaborative Participation Adaptation Model (CPAM) was used to culturally adapt a low-intensity, two-session group variant of the Triple P-Positive Parenting Program for Māori parents of young children in New Zealand. CPAM involved collaborating closely with Māori tribal elders, practitioners as end-users, and parents as consumers through a participatory process to identify content and delivery process used in Triple P that would ensure that traditional Māori cultural values were incorporated. The culturally adapted program (Te Whānau Pou Toru) was then evaluated with 70 parents of 3-7-year-old children in a two-arm randomized clinical trial (intervention vs waitlist control). Results showed that parents in the intervention group reported significantly greater improvements in child behavior problems and reduced interparental conflict about child-rearing compared to parents in the control group at immediate post-intervention. These intervention effects were either maintained or improved further at follow-up assessment. At 6-month follow-up intervention-group parents reported significantly greater reductions in overreactive parenting practices and greater confidence in managing a range of difficult child behaviors than control parents. The culturally adapted program was associated with high levels of parental satisfaction. Findings are discussed in terms of making brief, effective, culturally adapted parenting support available to Māori families
Experiences of parents whose children participated in a longitudinal follow‐up study
Abstract Background Long‐term follow‐up is necessary to understand the impact of perinatal interventions. Exploring parents' motives and experiences in consenting to their children taking part in longitudinal studies and understanding what outcomes are important to families may enhance participation and mitigate the loss to follow‐up. As existing evidence is largely based on investigators' perspectives using Western samples, the present pilot study explored parents' perspectives in a multicultural New Zealand context. Methods Data were generated using semi‐structured interviews with parents whose children had participated in a longitudinal study after neonatal recruitment. Parents' experiences of being part of the study were analysed thematically using an inductive approach. Results Parents (n = 16) were generally happy with the outcomes measured. Additionally, parents were interested in lifelong goals such as the impact of parental diabetes. We identified three themes: (1) Facilitators: Research participation was aided by motives and parent and research characteristics such as wishing to help others and straightforward recruitment; (2) Barriers: A hesitancy to participate was due to technical and clinical research aspects, participation burden and cultural barriers, such as complex wording, time commitment and nonindigenous research and (3) Benefits: Children and parents experienced advantages such as the opportunity for education. Conclusions Parents reported positive experiences and described the unexpected benefit of increasing families' health knowledge through participation. Improvements for current follow‐up studies were identified. Different ethnicities reported different experiences and perspectives, which warrants ongoing research, particularly with indigenous research participants. Patient or Public Contribution No active partnership with parents of patients took place
Predicting positive outcomes and successful completion in an online parenting program for parents of children with disruptive behavior : An integrated data analysis
Online delivery of parenting support is steadily increasing, yet the factors that influence program engagement and efficacy are still understudied. This study used an integrated data analysis approach to identify family and program-related factors that influence outcomes. We combined individual data from seven published efficacy trials of the web-based version of the Triple P—Positive Parenting Program. Data were analyzed for 985 families with children aged between 2 and 12 years (M = 4.87; SD = 2.14) using a Latent Change Score approach. At post-intervention, sociodemographic factors were not predictive of changes in child behavior problems, while parents of boys and those with higher education showed greater improvements in dysfunctional parenting. Parents who were initially more confident in their parenting showed more overall gains while parents with more initial adjustment difficulties showed less improvement. Only the effect of baseline child behavior problems on changes in dysfunctional parenting was moderated by treatment condition. At follow-up, program variant and completion were the primary outcome predictors, with completion found to be related to initial parenting confidence, internet usage and program variant. The implications of these findings for reaching and retaining parents in online programs across all phases of the engagement process are discussed.</p
Different Approaches to requesting Consent for Routine data linkage in Neonatal follow-up (ACORN): protocol for a 2×2 factorial randomised trial
Introduction Routinely collected data can be linked to research data to create a rich dataset and inform practice. However, consent is normally required to link identifiable data. Reported rates of consent to data linkage for children ranged from 21% to 96%, but no studies have investigated different approaches to seeking consent for data linkage for school-age children.Methods and analysis The Approaches to Consent for Routine Data Linkage in Neonatal Follow-up (ACORN) trial is a 2×2 factorial randomised trial to assess whether, for children who participated in neonatal randomised trials (pre-hypoglycaemia Prevention with Oral Dextrose Gel (hPOD), hPOD and The Impact of Protein Intravenous Nutrition on Development in Extremely Low Birth Weight Babies (ProVIDe)) and are approached to participate in an in-person assessment at 6–7 years of age, parental consent to data linkage is higher if consent is sought (1) after the in-person assessment (delayed) or concurrently and (2) for health and education data combined or separately. The primary outcomes will be rates of consent to linkage of (1) either health or education data and (2) both health and education data. A pilot study indicates the potentially available cohort size of 2110 (80% follow-up of the neonatal trial cohorts) would be adequate to detect an absolute difference of 6%–5%–4% from a baseline consent rate of 70%–85%–90%, respectively (2-tailed alpha 0.05, 90% power). With at least 1136 participants, the ACORN trial would have 90% power to detect an absolute difference of 5% in the primary outcome for each factor, assuming a consent rate of 90% in the control groups and alpha 0.05. Data are categorical and will be presented as number and per cent. The effects of factors will be tested using generalised linear models and presented as ORs and 95% CIs.Ethics and dissemination Ethics approval by the New Zealand Health and Disability Ethics Committee (19/STH/202). Dissemination will be via peer-reviewed publications, scientific meetings, educational sessions and public fora.Trial registration number ACTRN12621000571875 (Australian New Zealand Clinical Trials Registry)

Beneficial Effects of a Dietary Weight Loss Intervention on Human Gut Microbiome Diversity and Metabolism Are Not Sustained during Weight Maintenance
Objective: In the present study, we examined the effect of a very low-calorie diet(VLCD)-based obesity program on human gut microbiome diversity and metabolism during weight loss and weight maintenance. Methods: Obese subjects underwent 3 months of VLCD followed by 3 months of weight maintenance. A lean and an obese control group were included. The microbiome was characterized by performing high-throughput dual-indexed 16S rDNA amplicon sequencing. Results: At baseline, a significant difference in the Firmicutes/Bacteroidetes ratio between the lean and obese individuals was observed (p = 0.047). The VLCD resulted in significant alterations in gut microbiome diversity from baseline to 3 months (p = 0.0053). Acinetobacter represented an indicator species for the observed effect (indicator value = 0.998, p = 0.006). Metabolic analyses revealed alterations of the bacterial riboflavin pathway from baseline to 3 months (pnom = 0.0078). These changes in diversity and bacterial metabolism induced by VLCD diminished during the weight maintenance phase, despite sustained reductions in body weight and sustained improvements of insulin sensitivity. Conclusion: The present data show that a VLCD is able to beneficially alter both gut microbiome diversity and metabolism in obese humans, but that these changes are not sustained during weight maintenance. This finding might suggest that the microbiome should be targeted during obesity programs
